The Goliath CNC machine represents a significant advancement in portable subtractive manufacturing, offering a compact, autonomous solution for on-site material processing. This innovative router eliminates the traditional constraints of fixed work areas, enabling large-scale projects directly on the jobsite.
Developed by the Italian company Springa, the Goliath CNC was introduced via a successful crowdfunding campaign, quickly gaining traction within the maker community and professional woodworking sectors. Its design prioritizes mobility and ease of use, making advanced digital fabrication accessible in diverse environments.
Autonomous Wheeled Routing and Sensor-Guided Precision
The Goliath CNC operates as an autonomous robotic tool, utilizing three omnidirectional wheels to navigate directly across the workpiece surface. This unique mobility allows the router to move freely and execute cuts without being limited by a gantry or fixed frame.
Central to its operation is a patented sensor system that continuously triangulates the robot’s position on the material. These sensors update Goliath’s location relative to the work area 100 times per second, ensuring a high degree of accuracy and precision.
The system boasts a target accuracy of 0.1 mm (0.004 inches) and a repeatability of 0.004 inches, rivaling many stationary CNC machines. This precision is maintained even when encountering slight surface irregularities, as the machine’s weight helps to keep the panel flat beneath it.
An integrated self-correcting algorithm underpins its autonomous movements, compensating for any deviations or errors in real-time. This includes managing toolpaths to prevent wheels from falling into already cut pockets, ensuring continuous and level operation.

The Goliath CNC excels in large-panel mobile cutting, effectively removing the work area limitations inherent in traditional desktop CNC machines. Its sensor system provides a standard work area of approximately 9.8 x 8.5 feet (3 x 2.5 meters), which can be virtually extended by repositioning the robot and sensors.
This expansive capability makes it ideal for fabricating human-scale projects, such as furniture components, custom shelving units, and decorative panels, directly from full sheets of material like plywood or MDF. The machine’s portability allows it to maneuver around large workpieces with ease.
The machine supports a maximum cutting depth of 1.3 inches (35 mm), depending on the material and chosen mill bit. It is compatible with various materials, including wood (plywood, MDF, bamboo, solid wood), plastic sheets, and thin layers of aluminum.
With a compact footprint of 15.75″ L x 15.75″ W x 11.82″ H and a weight of 33 lbs (15 kg), the Goliath is designed for easy transport and storage. Built-in handles further enhance its mobility, allowing it to be carried to different jobsites or stored efficiently in smaller workshops.
Cable-Free Operation and Modern Engineering Practices
The Goliath CNC integrates a wireless connection system, enabling users to upload designs and supervise work progress remotely via a computer, smartphone, or tablet. This cable-free jobsite routing enhances operational flexibility and convenience.
The sensors themselves are battery-powered, offering up to 10 hours of operation on a single charge, further contributing to the system’s untethered functionality. The main unit operates on 120V or 230V AC power, with a total power consumption of approximately 1kW.
Modern engineering practices in 2026 emphasize sustainability, user experience, and AI integration in CNC operations. The Goliath aligns with these trends by offering a compact, efficient tool that reduces the need for large, energy-intensive stationary equipment.
AI-driven toolpath logic and adaptive cutting technologies are becoming standard, allowing machines to optimize performance in real-time based on material properties. While the Goliath’s core software, Slingshot, generates G-code from SVG files, future integrations with advanced AI CAM systems could further enhance its autonomous capabilities.
Technical Specifications and Performance Parameters
Understanding the core technical specifications of the Goliath CNC is crucial for optimizing its performance in various applications. The machine’s design focuses on balancing portability with robust cutting capabilities.
The spindle, a critical component, provides 710W of power and operates within an RPM range of 13,000 to 33,000. It utilizes an ER11 collet, compatible with 6mm and 1/4 inch bits, and can accommodate collets up to 8mm.
For typical woodworking applications, recommended feeds and speeds vary by material. For hardwoods like oak or maple, an RPM of 16,000-18,000 and a feed rate of 80-120 IPM are common, with a chip load of 0.003-0.004 IPT. Plywood often allows for higher feed rates, around 100-140 IPM, at similar RPMs.
